I don't know if it is available or even possible. I am on vacation right now with my iPhone and iPad ... Both have sim trays etc, but I am using my phone as a hotspot to get net access to my iPad. What would be even nice in such scenarios would be if I could utilise both arials in both pieces of hardware since i have them to increase the range or speeds of data. It seems a shame to have the hardware of 2 units, but only the power of one.
